Newsletter for businesses: how to create one people actually want to read

Almost every business I talk to in Málaga has at some point thought about setting up a newsletter for their company, and many are held back by the same doubt: what am I going to write about every month? And what if nobody opens it? It is a reasonable fear, because we all have an inbox full of newsletters we delete without a glance. But a well-made newsletter is one of the most profitable tools a business can have: it puts you directly into your customers' heads on a regular basis, without depending on algorithms or paying for every impact.

In this guide I tell you, from my experience building these systems for local businesses, how to create a newsletter people genuinely want to read. We are going to look at what to write about so you never run dry, how often to send it, how to write subject lines that get opened, how to measure whether it works and what mistakes to avoid. No magic formulas and with examples designed for a business your size, not for a multinational with a team of copywriters.

A newsletter is an owned channel, and that is its greatest virtue. When you post on social media, an algorithm decides how many followers your message reaches, and it is usually a very small fraction. When you send a newsletter, you enter the inbox of someone who has given you permission to speak to them. It is a much more personal and direct space, and nobody can take that access away or charge you for each send.

Beyond reach, the newsletter fulfils a role no one-off sale achieves: it builds a long-term relationship. Most of your customers are not ready to buy from you today, but if you show up every month in their inbox offering something useful, when the moment to buy arrives they will think of you before anyone else. It is the difference between being a stranger and being the brand they already trust. And that trust, in a local business, is almost everything.

The blank-page block is what kills the most newsletters before they are born. The solution is to stop thinking you have to sell in every email and start thinking about what is useful or interesting to your customer. Once you shift the focus, the ideas appear on their own. These are the types of content that work best:

• Practical tips from your sector: if you run a clinic, how to look after your health; if a shop, how to get the most out of your products.
• Real customer stories: cases of people you have helped, which build trust and provide social proof.
• Business news: a new product, a service, a change of hours or an improvement your customers want to know about.
• Behind the scenes: the day-to-day of your business, your team, how you work. It humanises the brand and hooks people.
• Exclusive offers and promotions: discounts only for subscribers, which reward those who read you and trigger sales.
• Key dates: reminders and content tied to seasons relevant to your business.

A trick that works very well is the eighty-twenty rule: around eighty percent of your content should add value and only twenty percent should sell directly. If every email you send is an offer, people learn to ignore you. If most of your emails genuinely help them, they will also open the ones with a promotion, because they have learned that your messages are worth it.

This is the question I get asked the most, and the honest answer is: the frequency you can keep up with quality. It is far better to send a good monthly newsletter consistently than to promise yourself a weekly one, burn out by the third week and disappear for six months. Consistency matters more than quantity, because it builds a habit in your subscriber.

For most local businesses, a monthly or fortnightly frequency is the sweet spot: enough for them not to forget you, but without flooding the inbox. If you have plenty to say and the resources to do it well, you can go up to weekly. What you must never do is send only when you want to sell something: if your subscribers only hear from you when there is an offer, they will associate your brand with always wanting to take their money.

A newsletter only works if it gets opened, and what decides the opening is the subject line. It is the cover of your message. A good subject line is short so it shows in full on mobile, sparks curiosity or promises a concrete benefit, and sounds like a person, not an advertising leaflet. Then the content has to deliver what the subject promised, or next time they will not open it.

1. 1Write the way you speak: your newsletter should sound like one person writing to another, not a cold corporate announcement.
2. 2Get to the point: respect the reader's time. A clear, direct message is appreciated more than an endless text.
3. 3Use the subscriber's name when you can: personalising increases closeness and opens.
4. 4Look after the preview text (preheader): that line next to the subject is a second chance to hook, don't leave it empty.
5. 5Close with a single clear call to action: what you want the person to do when they finish reading.

As for the design, less is more. More than half your emails will be opened on mobile, so everything must look perfect on a small screen: a single column, legible text and big buttons. Do not overuse heavy images, because many email clients block them by default. And keep the technical side of deliverability firmly in mind: setting up your domain authentication properly makes your emails reach the inbox and not the spam folder, a job worth doing from the start by following best practices such as those in Google's guidelines for senders

The great advantage of email over other channels is that almost everything can be measured. But do not drown in data: for a local business newsletter, it is enough to watch a few metrics and understand what each one tells you. What matters is not the number of a single send, but the trend over time.

• Open rate: what percentage opened the email. It tells you about the quality of your subject line and your reputation as a sender.
• Click rate: what percentage clicked a link. It measures whether the content and the call to action hook people.
• Unsubscribe rate: how many people unsubscribe. A spike warns you that you send too much or that the content is not interesting.
• List growth: if you add more subscribers than you lose, your newsletter is on the right track.

If a type of subject line opens more, repeat it. If a topic generates a lot of clicks, give it more space. The newsletter is a cycle of testing, measuring and improving. And do not forget that email feeds off your online reputation: a good newsletter can be the ideal place to ask for reviews, which pairs very well with what I explain in how to get reviews on Google, because the customers who read you and trust you are the ones who rate you best.

I have seen many newsletters die for the same reasons, and almost all of them are avoidable. Knowing them in advance saves you losing subscribers that took a lot to get. These are the most common slip-ups:

• Selling in every email: if you only send offers, people learn to ignore you or unsubscribe.
• Being irregular: appearing and disappearing breaks the habit and makes your subscribers forget you.
• Writing for yourself, not the reader: talking only about your business instead of what interests whoever reads.
• Boring or misleading subject lines: the first don't get opened, the second burn trust forever.
• Buying lists or adding people without permission: it is illegal, damages your reputation and those people will never read you.

The underlying mistake, from which almost all the others are born, is thinking of the newsletter as a channel to sell instead of a channel to look after the relationship. As soon as you shift the focus and ask yourself in every email what this brings to whoever reads it, most of these problems disappear on their own.

If you take one idea from this guide, let it be this: a good newsletter is not a leaflet you send when you want to sell, but a regular appointment where you look after the relationship with your customers by offering them value. Done this way, it becomes one of the most profitable and lasting channels in your business, because it builds trust month by month and keeps you present for when the moment to buy arrives.
